Problems solved by technology

[0002] In the process of overhauling the tail of a large aircraft, due to its high height, it is necessary to set up multi-layer overhaul platforms with different heights during the overhaul process. The overhaul platform has a blind spot in the coverage of the aircraft tail, and it is impossible to conduct a comprehensive overhaul; in addition, when the overhaul is completed and it needs to be disassembled, it also has the problem of a large workload

Embodiment Construction

[0041] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] see Figure 1-12 , a lifting platform for vertical tail maintenance of an aircraft, which includes a lower platform 1, a movable working ladder 2 is arranged on the top of the lower platform 1, and a derrick structure for installing an upper platform lifting device 5 is fixed on the top side of the lower platform 1 3. An upper platform 6 with a cantilever structure is fixed on the side wall of the top platform lifting device 5; a locking mechanism 4 for locking it is installed between the upper platform lifting device 5 and the derrick structure 3. By adopting the lifting platform with the above-mentioned structure, it adopts left-right symmetrical arrangement during use, and the two sub-platforms can be docked and combined. Each sub-platform consists of an upper platform, a lower platform, a derrick structure and a movable working ladder; the pla...

Abstract

The invention provides a lifting platform for airplane vertical fin overhauling. The lifting platform comprises a lower-layer platform. A movable work ladder is arranged on the top of the lower-layerplatform. A well frame structure for installing an upper-layer platform lifting device is fixed to the side edge of the top of the lower-layer platform. An upper-layer platform of a cantilever structure is fixed to the side wall of the upper-layer platform lifting device. A locking mechanism used for locking the upper-layer platform lifting device and the well frame structure is arranged between the upper-layer platform lifting device and the well frame structure. The lifting platform can be used for overhauling large airplane tail wings, the lifting platform can be conveniently controlled toascend and descend, so that different overhauling heights are achieved, the tail wing overhauling usage requirement of the lifting platform is met, the overhauling safety is guaranteed, meanwhile, thelabor intensity of operators is greatly lowered, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of aircraft maintenance tooling platform equipment, in particular to a lifting platform for aircraft vertical tail maintenance. Background technique [0002] In the process of overhauling the tail of a large aircraft, due to its high height, it is necessary to set up multi-layer overhaul platforms with different heights during the overhaul process. The overhaul platform has a blind area in the coverage of the aircraft empennage, and it cannot be easily overhauled; in addition, when the overhaul is completed and it needs to be disassembled, it also has the problem of a large workload. Therefore, need to design a kind of lifting platform that is convenient to aircraft empennage maintenance. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a lifting platform for aircraft vertical tail maintenance. This lifting platform can be used for the maintenance of ...
